FAQ

This thermostat is commonly used on dishwashers from Whirlpool, Kenmore, KitchenAid, Amana, and Maytag. Search results also associate this part family with some models from Crosley, Estate, Inglis, Jenn-Air, Magic Chef, and Roper. Because dishwasher model coverage varies by series, the safest way to confirm fit is to match your original part number or verify compatibility by your exact model number.
This part cross-references to 661566, WP661566, 3371618, W10339474, AP6010246, PS11743423, 3369777, 3370783, 4171694, WP661566VP, and 2887. Matching one of these numbers on your original thermostat or parts list is a strong indicator of compatibility.
The high limit thermostat is a temperature safety device. It helps protect the dishwasher from overheating by opening the circuit if the temperature rises too high. In many Whirlpool-family dishwashers, it works as part of the heater protection system, so if it fails open, the dishwasher may stop heating properly.
Typical symptoms include no heat during the wash or dry cycle, dishes not drying well, water not reaching normal wash temperature, longer cycle performance issues, or a dishwasher that seems to run but leaves dishes wet and poorly cleaned. Since similar symptoms can also be caused by a failed heating element, wiring issue, or control problem, diagnosis with a meter is recommended before replacing the thermostat.
On many compatible dishwashers, this is a moderate repair that usually takes about 20 to 45 minutes. You typically disconnect power, shut off water if needed for access, remove the lower access or toe panel, locate the thermostat on or near the tub/heater circuit area, transfer the wire connectors, and reinstall the new part. Common tools include a screwdriver, nut driver, and possibly needle-nose pliers. Always disconnect power first to avoid electrical shock.
Before replacement, inspect the wiring terminals for heat damage or corrosion, check the heating element for continuity or visible damage, and make sure the connectors fit tightly on the thermostat terminals. If the old thermostat failed because of overheating, also inspect for control or heater relay issues that could cause excessive heat. Verifying the old part number and comparing the terminal layout before installation can help avoid a mismatch.
